Random audio playing and can't shut it off

This has been happening for several months and I have no idea what to do. Random audio will start playing on my computer, mostly ads, but sometimes it sounds like videos or news or people talking. It happens even when all my browser windows are closed and I have no applications running. It has even woken me up in the middle of the night after I thought my computer was asleep.

I've opened task manager and can't find the problem. Many times as soon as I open task manager, it stops so it's hard to catch. It usually lasts for less than 2 minutes, but today it just kept going for 15 minutes or so. It will stop doing this for weeks at a time, then randomly come back.

I have not downloaded anything recently or installed any new software. I have Norton Internet Security and I've scanned several times with Malwarebytes and it comes up with nothing. I've checked running services, startup, sounds, etc.- nothing comes up. It is incredibly frustrating.

I am running Windows 7.

I read on another forum someone had a similar problem and it was a process "indt2.sys" but I don't even have that process anywhere.

Run ESET & post the log please. This scan may take a very long while, so please be patient. Start it before going to work or bed.http://www.eset.com/us/online-scann...http://www.eset.com/home/products/o...You may have to download ESET from a good computer, put it on a thumb drive & run it from there.http://kb.eset.com/esetkb/index?pag...Configure ESET this way & disable your AV.http://i.imgur.com/3U7YC.gifHow to Temporarily Disable your Anti-virushttp://www.bleepingcomputer.com/for...Why Would I Ever Need an Online Virus Scanner?I already have an antivirus program installed, isn't that enough?http://www.squidoo.com/the-best-fre...Once onto a machine, malware can disable antivirus programs, prevent antimalware programs from downloading updates, or prevent a user from running antivirus scans or installing new antivirus software or malware removal tools. At this point even though you are aware the computer is infected, removal is very difficult.5: Why does the ESET Online Scanner run slowly on my computer?If you have other antivirus, antispyware or anti-malware programs running on your computer, they may intercept the scan being performed by the ESET Online Scanner and hinder performance. You may wish to disable the real-time protection components of your other security software before running the ESET Online Scanner. Remember to turn them back on after you are finished.17: How can I view the log file from ESET Online Scanner?http://kb.eset.com/esetkb/index?pag...http://www.eset.com/home/products/o...The ESET Online Scanner saves a log file after running, which can be examined or sent in to ESET for further analysis. The path to the log file is "C:\Program Files\EsetOnlineScanner\log.txt". You can view this file by navigating to the directory and double-clicking on it in Windows Explorer, or by copying and pasting the path specification above (including the quotation marks) into the Start ? Run dialog box from the Start Menu on the desktop.

It wouldn't hurt at all to run the three tools that XPuser4real suggests. One scanner might miss something, and you have some nasty Trojans found already. Leaving any traces behind can cause reinfection. (I know Johnw will not be relying on that one scan. And all pc's should have Malwarebytes installed on them for extra protection)

"I'll just have to wait and see if it worked"No one program will remove everything, ESET is just the beginning of the process, remnants left will once again infect the comp & slowly invade deeper & deeper.

I have Malwarebytes installed and run a full scan at least once a week. It didn't pick up any of the other stuff. I had Norton Internet Security installed until two days ago, when I got fed up with it. It always fails and I have to reinstall it and I don't have time to do that every other week. I was going to wait and see if I had any more problems with the audio thing before downloading and running the other three programs, but I guess I'll do it anyway. It kind of surprises me that Malwarebytes didn't catch anything. I always thought they were the most thorough. OK, I'll post the results of the other 3 programs as I get them. It might be a day or two since I don't know how much time they will take to run. Thanks.

Oh, I just realized that Malwarebytes was one of the three you listed. Well, so we already know that didn't find anything. I just downloaded the other two, but while I was downloading the first one, I got a strange message saying the it failed to save because it wouldn't save to the desktop because that file couldn't be altered or something along those lines, which I have never had before. I always save to the desktop when I download from online so I had to change the destination folder and it worked. I don't know what that was about.

OK, well, this all took a lot less time than I anticipated, obviously. So I ran the other one and it says I have to reboot, but I'm really, really nervous about doing so because it says that it the hard disk was infected and something about rootkit.boot and if it doesn't work, I'm worried my computer won't reboot at all. There is no log file that I can see yet, so I took a screenshot of the results. I can't figure out how to insert the image into this post so I'm just going to post the link.

Please copy & paste instructions into a text file, print steps & info. You will need them, as they are hard to remember, for when you are offline.

Note: Is your important stuff backed up, including your emails & address book? Anything can happen, during the clean up.

The badies are always ahead of the goodies, be aware, this can be a very long process, involving many different tools to clean up an infected comp.Some infections are irremovable.Very Important: Malware infections can possibly lead to identity theft, stolen bank funds, misuse of credit card information etc.The use of the computer is the primary factor in the decision whether to re-format and re-install, or just disinfect.http://www.dslreports.com/faq/10063How to report ID theft, fraud, drive-by installs, hijacking and malware?http://www.dslreports.com/faq/10451Change your router password if it is not strong or still uses the default one.Hack lets intruders sneak into home routershttp://tinyurl.com/4pz64fchttp://compnetworking.about.com/od/...

As we dismantle the infection bit by bit, that may allow the repeat use of programs, which may in turn pick up more.Removal of infected parts of the system, may cause other parts to stop working, such as your Internet connection or Services. These then we have to repair.

1: Download & run Unhidehttp://www.bleepingcomputer.com/for...http://download.bleepingcomputer.co...Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run, it does take some time, be patient. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.

4: Run ComboFix http://www.bleepingcomputer.com/dow...http://download.bleepingcomputer.co...http://www.techsupportforum.com/sec...http://www.forospyware.com/sUBs/Com...A guide and tutorial on using ComboFixhttp://www.bleepingcomputer.com/com...Note:Do not mouseclick combofix's window while it is running. That may cause it to stall.If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.Can't Install an Antivirus - Windows Security Center still detects previous AVhttp://www.experts-exchange.com/Vir...We are almost ready to start ComboFix, but before we do so, we need to take some preventative measures so that there are no conflicts with other programs when running ComboFix. At this point you should do the following: * Close all open Windows including this one. * Close or disable all running Antivirus, Antispyware, and Firewall programs as they may interfere with the proper running of ComboFix. Instructions on disabling these type of programs can be found in this topic.http://www.bleepingcomputer.com/for...Once these two steps have been completed, double-click on the ComboFix icon found on your desktop. Please note, that once you start ComboFix you should not click anywhere on the ComboFix window as it can cause the program to stall. In fact, when ComboFix is running, do not touch your computer at all. The scan could take a while, so please be patient.
